Most people compare refinance offers by looking at one number. The rate. It is the number lenders put in big type, and the one a friend asks about first, so it ends up feeling like the whole decision. The trouble is that the rate alone cannot tell you which offer actually costs you less. The math that does is sitting right there on a form you are entitled to receive, and once you know where to look, comparing a mortgage refinance becomes a calm, side-by-side exercise instead of a guess.
This guide walks through how to read and compare Loan Estimates so you can judge a refinance on its full cost rather than its headline rate. The numbers and form sections below come straight from the Consumer Financial Protection Bureau, which designed the form to make exactly this comparison possible.
What a Loan Estimate is, and why it exists
A Loan Estimate is a standardized three-page form a lender must give you within three business days of receiving your application. Every lender uses the same layout, with the same sections in the same order. That is the point. Before this form existed, comparing offers meant lining up documents that each looked different and hoping you were reading the same line on both. The standard form took that confusion away, as the CFPB's Loan Estimate explainer describes.
For a refinance, the same rules apply. You can request a Loan Estimate from more than one lender, and because the forms match, you can set them next to each other and read straight across. One caution from the CFPB matters here. Request estimates for the same kind of loan. A 30-year fixed compared against a 15-year fixed will not tell you anything useful, because you are comparing two different products, not two prices for the same thing.
The rate is on page 1. The real cost is on page 3.
Here is the part the headline rate hides. Your interest rate sits on page 1, under Loan Terms. The number that tells you what the loan actually costs over time, the APR, sits on page 3, under Comparisons. They are not the same thing, and the gap between them is where the truth lives.
The CFPB explains that the APR expresses your costs over the loan term as a rate. It folds in fees and certain charges that the interest rate by itself leaves out. Two offers can show the same interest rate and carry different APRs, and when they do, the one with the higher APR is the more expensive loan. A low rate paired with heavy fees is the trap. The APR is the tool that exposes it.
This is the reframe worth holding onto. A good low rate is not the trophy. It is one input. The full cost is the thing you are actually buying, and the form is built to show it to you.
The single most useful line: "In 5 Years"
If you read only one comparison line, read this one. On page 3, in the Comparisons section, there is a line labeled "In 5 Years." It shows the total dollar amount, including principal, that you will pay over the first five years of the loan. The CFPB points out that borrowers keep a mortgage for about five years on average before they move or refinance again, which is why this line is such an honest yardstick.
It works because it is in dollars, not percentages. A rate is abstract. A five-year total is concrete. Put two Loan Estimates side by side, find the "In 5 Years" figure on each, and the cheaper offer over a realistic holding period stops being a matter of opinion. For a refinance, where you are weighing upfront costs against monthly savings, this number quietly settles a lot of arguments.
Where the costs actually differ
Not every fee on a Loan Estimate is something a lender controls. Some, like recording fees or certain third-party charges, are fixed no matter who you borrow from. The fees that separate one offer from another live in a few specific places, and these are the lines worth your attention. The CFPB's guide to reviewing Loan Estimates points to them directly.
Section A: Origination charges
This is what the lender charges to make the loan, including any points you pay to lower your rate. Origination charges vary a lot between lenders, so this section rewards a close read. A rate that looks low can be bought down with points that show up here, which is another reason the rate on its own misleads.
Section B: Services you cannot shop for
These are services the lender selects, such as an appraisal. You cannot pick the provider, but you can still compare what each lender lists, because the choices differ.
Section J and lender credits
Lender credits reduce your closing costs, usually in exchange for a higher rate. They are not free money. They are a trade, and seeing them on the form lets you decide whether that trade fits your timeline.
Cash to close
On page 2 you will find the cash to close, the actual amount you need at the table. For a refinance this figure tells you how much of the cost you are paying out of pocket versus rolling into the loan, which feeds directly into your break-even math.
The break-even question every refinance comes down to
A refinance has a cost, and that cost buys you a lower payment. The question that decides whether it is worth doing is how long it takes the savings to pay back the cost. Add up the closing costs from your Loan Estimate. Divide that by the amount your monthly payment drops. The result is the number of months to break even.
If your costs are $4,000 and your payment falls by $200 a month, you break even in 20 months. Stay in the home past that point and the refinance earns its keep. Sell or refinance again before it, and you may have spent more than you saved. This is your math, built from your own numbers, and it does not depend on where rates happen to sit on any given day. It depends on the cost of the loan in front of you and how long you plan to keep it.
A quick note on the "no-closing-cost" refinance, since it comes up often. As the CFPB explains, those costs do not vanish. They are usually folded into your loan balance or paid for with a higher rate. The Loan Estimate still shows you the full picture, which is why reading it carefully protects you.
Having more than one estimate is your strongest position
There is a practical reason to gather more than one Loan Estimate beyond the comparison itself. According to the CFPB, having estimates from more than one lender in hand is your best bargaining chip. A lender can match or beat another offer, or explain plainly why its numbers differ. Either way, you learn something. You are not being difficult by asking. You are doing exactly what the form was created to let you do.
Smart, careful people skip this step all the time, not because they are careless but because the system rarely invites the comparison. The rate gets advertised. The full-cost lines do not. Knowing where they are puts the advantage back on your side of the table.
How GoodLoan approaches the comparison
We would rather you understand your Loan Estimate than take our word for anything. When you talk to a GoodLoan loan officer about a refinance, we will walk through the form line by line with you, point you to the APR and the "In 5 Years" figure, and run your break-even with your real numbers. If the math does not favor a refinance for your situation, we will tell you that. We say no a fair amount, because a refinance that does not pay off is not a service to anyone.

Frequently asked questions
Is the lowest rate always the cheapest refinance?
No. A low rate can come with high origination charges or points that raise your total cost. Compare the APR on page 3 and the "In 5 Years" figure, both of which fold in fees, rather than judging by the interest rate alone.
What is the difference between the interest rate and the APR?
The interest rate is the cost of borrowing the principal, shown on page 1. The APR expresses your costs over the loan term as a rate and includes certain fees, shown on page 3. When two offers share a rate but differ in APR, the higher APR is the more expensive loan.
How many Loan Estimates should I get for a refinance?
Getting more than one lets you compare on equal footing and gives you room to negotiate. Request estimates for the same loan type and term so the forms line up cleanly.
What does "cash to close" mean on a refinance?
It is the amount you need to bring at closing, found on page 2. For a refinance it shows how much cost you are paying upfront versus rolling into the loan balance, which feeds your break-even calculation.
Are no-closing-cost refinances really free?
No. The costs are typically added to your loan balance or covered by a higher interest rate. The Loan Estimate still reflects the full cost, so reading it carefully tells you what you are actually paying.
How do I calculate my refinance break-even?
Divide your total closing costs by the amount your monthly payment drops. The answer is how many months it takes to recoup the cost. Compare that against how long you plan to keep the home to decide whether the refinance is worth it.
